PAM3102
General Description
The dual LDO PAM3102 series of positive voltage linear regulators feature high output voltage accuracy, low quiescent current and low dropout voltage, making them ideal for battery powered applications. The line transient response and load transient response are excellent. Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed. Space-saving SOT23-6 package for 2-ch LDOs is attractive for portable and handheld applications. They have both thermal shutdown and a current limit feature to prevent device failure under extreme operating conditions. They are stable with an output capacitance of 2.2 μ F or greater.
Output Accuracy: ± 2% Low Dropout Voltage: 180mV@150mA High PSRR: 70dB@100Hz Low Noise Output Current Limiting Short Circuit Protection Thermal Shutdown Space Saving Package SOT23-6 Pb-Free Package
